Rihanna & A$AP Rocky Board Old-Fashioned NYC Yellow Taxi for Mother’s Day

Rihanna and A$AP Rocky were feeling nostalgic in the Big Apple this weekend for Mother’s Day — hitting the town looking damn good … and then getting into this oldie-but-goodie.

The couple went out Sunday night in NYC for what looks to have been a parents-only date night … and aside from the fashion statement they were making while stepping out — par for the course, really — they also made a splash with their sweet ride … an old-school taxi.

Take a look … RiRi and Rocky boarded a big yellow cab that looks like it’s out of the 1970s — with the checkered bordering and everything. It’s like Bob De Niro was picking them up!

FWIW, taxi cabs do NOT look like this anymore … so this was definitely a custom order.

Still, you could say it was worth it … ’cause Rihanna and Rocky look pretty damn fabulous here, and the whole flashback scene is something to behold. BTW — somebody gave RiRi a vinyl copy of her “Rated R” album … and it seems she signed it from the back of the cab.

Like we said, no sign of the kiddos for this outing — although they were with their boys just a day earlier … celebrating RZA’s 2nd birthday that looked like a little kid’s dream come true.

Nothing like a little balance for Mama and Papa Bear … that’s what parenthood’s all about.
